Title: Basic gas-absorbing fiber and its production
Inventor: TANAKA KOJI
IPC: D06M101/16
Filed: 1996-01-11
Abstract: PURPOSE: To obtain a basic gas-absorbing fiber which shows a large absorption and high absorption rate of basic gas, has sufficient mechanical properties and can be readily regenerated, by specifying the increase of nitrogen content by hydrazine crosslinking and introduction of carboxyl groups and amide groups into the fiber. CONSTITUTION: An acrylic fiber produced from an acrylonitrile(AN) polymer containing more than 40wt.% of AN is crosslinked with hydrazine to increase the nitrogen content by 1.0-8.0wt.% by means of the hydrazine crosslinking. Then, the fiber is hydrolyzed to eliminate the residual nitrile group and introduce 2.0-6.0mmol/g of carboxyl groups and amide groups to the rest part to give this fiber with the tensile strength of higher than 1g/d, having excellent absorption power of basic gas.

Title: Removing device for sticking snow
Inventor: TAKANO TADASHI
IPC: H05B3/20
Filed: 1981-02-17
Abstract: PURPOSE:To prevent the local thermal deformation of an antenna mirror surface while removing sticking snow uniformly, by providing heat reflecting plates at the circumference of a heating body. CONSTITUTION:A couple of heat reflecting plates 24 and 25 are arranged surrunding a heating body 23. The major part of heat generated by the heating  body 23 and conducted to the heat reflecting plates 24 and 25 by irradiation is  reflected between the heat reflecting plates 24 and 25 by adequately selecting the material and shape of the heat reflecting plates 24 and 25 to be used for the temperature rise of the air layer between the heat reflecting plates. As a result,  the heated air layer flows along an antenna mirror surface 21 by natural convection to conduct the heat to the mirror surface 21 uniformly, so the mirror surface 21 at distance from the heating body 23 has the capability of removing  sticking snow uniformly. Further, the temperature rise of the mirror surface 21  is uniform, preventing the local thermal deformation of the mirror surface 21.
